This
EET
Chapter
will
introduce
you
to
visualization
capabilities
available
through
NASA's
Earth
Observatory.
You'll
build
several
animations
of
satellite
data
that
illustrate
carbon
pathways
through
the
Earth
system.
For
instance,
you'll
build
animations
of
fire
images
that
indicate
carbon
is
being
released
into
the
atmosphere.
You'll
also
make
animations
of
